Does anyone know if they are still supported? I put a call in to Tiffen but I'm guessing I won't get a return call today. (Hopefully, they won't call at 5 in the morning!)

Yes and no, I was told no parts were available but after I'd taken mine apart trying to glue it (wrong type of plastic to glue) I saw the part numbers on the inside of the two broken pieces (178-0053 and 178-0054 on mine) and found out they did have those parts.

You have to be persistent on the calls and not wait for a call back as you may not get it.
